Removal of microcystins from a waste stabilisation lagoon: evaluation of a packed-bed continuous flow TiO2 reactor.

Photocatalysis has been shown to successfully remove microcystins (MC) in laboratory experiments. Most research to date has been performed under ideal conditions in pure or ultrapure water. In this investigation the efficiency of photocatalysis using titanium dioxide was examined in a complex matrix (waste stabilisation lagoon water). A flow-through photocatalytic reactor was used for the photocatalytic removal of four commonly-occurring microcystin analogues (MC-YR, MC-RR, MC-LR, and MC-LA). Up to 51% removal for single MC analogues in waste lagoon water was observed. Similar removal rates were observed when a mixture of all four MC analogues was treated. Although treatment of MC-containing cyanobacterial cells of Microcystis aeruginosa resulted in no decline in cell numbers, or viability with the current reactor design and treatment regime, the photocatalytic treatment did improve the overall quality of waste lagoon water. This study demonstrates that, despite the presence of natural organic matter, the microcystins could be successfully degraded in a complex environmental matrix

Evaluation of Complementary-Alternative Medicine (CAM) questionnaire development for Indonesian clinical psychologists: a pilot study

This study aimed to evaluate questionnaire development to measure the knowledge of Complementary-Alternative Medicine (CAM), attitudes towards CAM, CAM experiences, and CAM educational needs of clinical psychologists in Indonesia. A 26-item questionnaire was developed through an extensive literature search. Data was obtained from provisional psychologists from the Master of Professional Clinical Psychology programs at two established public universities in urban areas of Indonesia. To validate the questionnaire, panel reviews by executive members of the Indonesian Clinical Psychology Association (ICPA), experts in health psychology, and experts in public health and CAM provided their professional judgements. The self-reporting questionnaire consisted of four scales including: knowledge of CAM (6 items), attitudes towards CAM (10 items), CAM experiences (4 items), and CAM educational needs (6 items). All scales, except CAM Experiences, were assessed on a 7-point Likert scale. Sixty provisional psychologists were eligible to complete the questionnaire with a response rate of 73% (N = 44). The results showed that the CAM questionnaire was reliable (Cronbach's coefficient alpha range = 0.62-0.96; item-total correlation range = 0.14-0.92) and demonstrated content validity. Following further psychometric evaluation, the CAM questionnaire may provide the evidence-based information to inform the education and practice of Indonesian clinical psychologists

Looking forward: career identity formation and the temporal orientations of young Australians

This paper provides insights into young people's experiences of transitions from adolescence into emerging adulthood by focusing on connections between their career identity formation, time perspectives, and future outlook. The data used in this paper are based on two sets of in-depth interviews undertaken with 28 young people when they were aged 16 and again at age 22. We have identified four main temporal orientations (time perspective/future outlook combinations) and describe how those patterns correspond to proposed extensions to the identity status model as it relates to career identity. Our findings offer support for the inclusion of postponement as a process of identity formation and hiatus as an additional identity status. We also observe three temporally based expressions of career identity achievement, which we label: temporary achievement, permanent achievement, and sequential achievement

Comparison of the collagen haemostat Sangustop(R) versus a carrier-bound fibrin sealant during liver resection; ESSCALIVER-study

Background: Haemostasis in liver surgery remains a challenge despite improved resection techniques. Oozing from blood vessels too small to be ligated necessitate a treatment with haemostats in order to prevent complications attributed to bleeding. There is good evidence from randomised trials for the efficacy of fibrin sealants, on their own or in combination with a carrier material. A new haemostatic device is Sangustop(R). It is a collagen based material without any coagulation factors. Pre-clinical data for Sangustop(R) showed superior haemostatic effect. This present study aims to show that in the clinical situation Sangustop(R) is not inferior to a carrier-bound fibrin sealant (Tachosil(R)) as a haemostatic treatment in hepatic resection. Methods: This is a multi-centre, patient-blinded, intra-operatively randomised controlled trial. A total of 126 patients planned for an elective liver resection will be enrolled in eight surgical centres. The primary objective of this study is to show the non-inferiority of Sangustop(R) versus a carrier-bound fibrin sealant (Tachosil(R)) in achieving haemostasis after hepatic resection. The surgical intervention is standardised with regard to devices and techniques used for resection and primary haemostasis. Patients will be followed-up for three months for complications and adverse events. Discussion: This randomised controlled trial (ESSCALIVER) aims to compare the new collagen haemostat Sangustop(R) with a carrier-bound fibrin sealant which can be seen as a "gold standard" in hepatic and other visceral organ surgery. If non-inferiority is shown other criteria than the haemostatic efficacy (e.g. costs, adverse events rate) may be considered for the choice of the most appropriate treatment.

Influence of Motivation and Quality of Work Life on The Performance of Employees

This examines the influence of motivation and quality of work life on employee performance CV. Prima Indo Tuna in Makassar. This type of research is explanatory attempt to explain the factors that affect the performance of the employees of the two factors, namely the motivation and the quality of working life. Respondents were 50 people who were employees at CV. Prima Indo Tuna Makassar on the processing or production either permanent or contract employee. Analysis of hypothesis verification regression analysis, which showed no significant influence between the variables of motivation and quality of work life on employee performance, it is proved by F count> 6,806 F table 3.20. From the analysis of the partial test proved that there is a significant influence on the variables of motivation and the quality of working life to the performance. Then the partial test results obtained by the partial determination coefficient (r2)of 0108 which shows motivation variable is the dominant variable affecting employee performance

Systemic, local, and imaging biomarkers of brain injury: more needed, and better use of those already established?

Much progress has been made over the past two decades in the treatment of severe acute brain injury, including traumatic brain injury and subarachnoid hemorrhage, resulting in a higher proportion of patients surviving with better outcomes. This has arisen from a combination of factors. These include improvements in procedures at the scene (pre-hospital) and in the hospital emergency department, advances in neuromonitoring in the intensive care unit, both continuously at the bedside and intermittently in scans, evolution and refinement of protocol-driven therapy for better management of patients, and advances in surgical procedures and rehabilitation. Nevertheless, many patients still experience varying degrees of long-term disabilities post-injury with consequent demands on carers and resources, and there is room for improvement. Biomarkers are a key aspect of neuromonitoring. A broad definition of a biomarker is any observable feature that can be used to inform on the state of the patient, e.g., a molecular species, a feature on a scan, or a monitoring characteristic, e.g., cerebrovascular pressure reactivity index. Biomarkers are usually quantitative measures, which can be utilized in diagnosis and monitoring of response to treatment. They are thus crucial to the development of therapies and may be utilized as surrogate endpoints in Phase II clinical trials. To date, there is no specific drug treatment for acute brain injury, and many seemingly promising agents emerging from pre-clinical animal models have failed in clinical trials. Large Phase III studies of clinical outcomes are costly, consuming time and resources. It is therefore important that adequate Phase II clinical studies with informative surrogate endpoints are performed employing appropriate biomarkers. In this article, we review some of the available systemic, local, and imaging biomarkers and technologies relevant in acute brain injury patients, and highlight gaps in the current state of knowledge.We gratefully acknowledge financial support as follows.

Use of T2-weighted magnetic resonance imaging of the optic nerve sheath to detect raised intracranial pressure.

INTRODUCTION: The dural sheath surrounding the optic nerve communicates with the subarachnoid space, and distends when intracranial pressure is elevated. Magnetic resonance imaging (MRI) is often performed in patients at risk for raised intracranial pressure (ICP) and can be used to measure precisely the diameter of optic nerve and its sheath. The objective of this study was to assess the relationship between optic nerve sheath diameter (ONSD), as measured using MRI, and ICP. METHODS: We conducted a retrospective blinded analysis of brain MRI images in a prospective cohort of 38 patients requiring ICP monitoring after severe traumatic brain injury (TBI), and in 36 healthy volunteers. ONSD was measured on T2-weighted turbo spin-echo fat-suppressed sequence obtained at 3 Tesla MRI. ICP was measured invasively during the MRI scan via a parenchymal sensor in the TBI patients. RESULTS: Measurement of ONSD was possible in 95% of cases. The ONSD was significantly greater in TBI patients with raised ICP (>20 mmHg; 6.31 +/- 0.50 mm, 19 measures) than in those with ICP of 20 mmHg or less (5.29 +/- 0.48 mm, 26 measures; P < 0.0001) or in healthy volunteers (5.08 +/- 0.52 mm; P < 0.0001). There was a significant relationship between ONSD and ICP (r = 0.71, P < 0.0001). Enlarged ONSD was a robust predictor of raised ICP (area under the receiver operating characteristic curve = 0.94), with a best cut-off of 5.82 mm, corresponding to a negative predictive value of 92%, and to a value of 100% when ONSD was less than 5.30 mm. CONCLUSIONS: When brain MRI is indicated, ONSD measurement on images obtained using routine sequences can provide a quantitative estimate of the likelihood of significant intracranial hypertension
